Method and apparatus for partially super-cooling a fluid

ABSTRACT

The present invention relates to a method and apparatus for super-cooling a contained fluid by exposing a portion of the contained fluid to a cooling substance while leaving a portion of the contained fluid uncooled. The present invention works by causing both convection and super-cooling. A container includes at least three sections: an insulated upper chamber, referred to as a cooling chamber, which holds a cooling substance or refrigerating apparatus; a second, lower chamber, referred to as the uncooled chamber; and at least one hollow chamber that extends through and is in contact with both cooling and un-cooled chambers. The hollow chamber, referred to as a containment chamber, receives the contained (i.e., bottled or canned or otherwise contained) fluid that is to be partially super-cooled. A horizontal plane divides the cooling chamber and the uncooled chamber. In some embodiments the containment chamber is oriented at an angle to the horizontal plane, so that the containment chamber extends through the upper (cooled) and lower (uncooled) chambers.

FIELD

The present disclosure relates to a method and apparatus that partially cools a fluid below its freezing point while maintaining the fluid in a liquid state by exposing a portion of a fluid container to a cooling substance. The process of cooling a fluid below its freezing point while maintaining its liquid state is known as super-cooling. A liquid at a temperature below its freezing point will crystallize in the presence of a seed crystal. or nucleus, around which a crystal structure can form, thus creating a solid. However. lacking any such nucleus, the liquid phase can be maintained down to a temperature below the liquid's freezing point. For example, water normally freezes at 0 degrees Celsius or 32 degrees Fahrenheit, however it can also be super-cooled at ambient pressure to temperatures below −40 degrees Celsius or −50 degrees Fahrenheit if the water is free of nuclei, such as water that has been sufficiently filtered as to be devoid of particulate that might act as a seed crystal.

Contained fluids have been known to reach super-cooled temperatures when the container is smooth and devoid of foreign particulate and the fluid and container are exposed to a cooling means capable of reaching a temperature below the freezing point of the contained liquid.

Modern beverage containment methods include the manufacture of unique containers for each contained beverage. Health and safety standards often dictate beverage liquids to be of pure, filtered nature. Pure, filtered liquid in a new container tends to provide the necessary conditions for super-cooling to occur.

One embodiment of the present disclosure relates to portable containers that cause a contained fluid(s) to be super-cooled by the exposing a portion of the container to a cooling substance, such as a separately contained bath of rock-salt and ice.

SUMMARY

The present invention relates to a method and apparatus for super-cooling a contained fluid by exposing a portion of the contained fluid to a cooling substance while leaving a portion of the contained fluid uncooled.

A container includes at least three sections: an insulated upper chamber, referred to as a cooling chamber, which holds a cooling substance; a second, lower chamber, referred to as the uncooled chamber; and at least one hollow chamber that extends through and is in contact with both cooling and uncooled chambers. The hollow chamber, referred to as a containment chamber, receives the contained (i.e., bottled or canned or otherwise contained) fluid that is to be partially super-cooled. A horizontally oriented plane divides the cooling chamber and the uncooled chamber. In some embodiments the containment chamber is oriented at an angle to the horizontal plane, so that the containment chamber extends through the upper (cooled) and lower (uncooled) chamber(s).

The present invention works by causing both convection and supercooling. Convection is achieved by exposing only part of the contained fluid to a cooling substance. Placing the contained fluid in the invention's hollow containment chamber exposes the contained fluid to both the upper, cooling chamber and the lower, uncooled chamber; in this way the fluid becomes partially cooled. The partial cooling results in convection. That is, the contained liquid moves from a warmer to a cooler part of its container.

The action of super-cooling is achievable because contained fluids such as currently marketed bottled or canned beverages are of a purity that allows super-cooling. Super-cooling can occur when a fluid that is devoid of particulates is cooled to a temperature below its freezing or crystallization point. Any liquid devoid of particulates can be cooled to a temperature that is below that liquid's freezing point because it is the presence of particulates in liquids that allows the binding which leads to crystallization. Thus a contained fluid in a clean, smooth container—for example a bottled or canned beverage—could be super-cooled, dropping to a below-freezing temperature. The present invention receives such contained fluids and causes this super-cooling. Two aspects of the present invention, the super-cooling plus the aforementioned convection, keep the contained fluids in their super-cooled, liquid state. In a context of beverages, the present invention provides a container for super-cooling and storing a contained fluid (for example a beverage) for a convenient period of time in which beverages may be stored and consumed.

One skilled in the art will realize that a cooling substance may include a powered cooling system such as a refrigerant and compressor combination or may be a chemical combination that produces low temperatures such as rock salt and ice.

The present invention offers improvements to the prior art by permitting super-cooling of contained fluids to extremely chilled liquid states while avoiding solid freezing. It also keeps contained fluids separate from any cooling substance (such as ice-and-rock-salt mixtures), allowing, for example, enjoyment of a canned or bottled beverage which has no taste of rock salt, and with no unwanted ice or water on the beverage bottle or can.

The details of one or more variations of the instant subject matter are set forth in the accompanying drawings and the description below. Other features and advantages of the instant subject matter will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION OF DRAWINGS

FIG. 1 is a cross-section of the present embodiment 10. An apparatus and method for cooling a portion of a contained fluid is described. The fluid-cooling apparatus comprises an enclosure 11. The enclosure 11 further comprises an upper chamber 26 and a lower chamber 13. A containment chamber 22 is partially surrounded by walls of the upper chamber 20 and is further surrounded by walls 21 of the lower chamber 13. A cooling substance creates a bath 28 contained within the upper chamber 26. The bath is capable of producing temperatures below the freezing point of the fluid to be cooled. The lower chamber 13 remains empty or uncooled. Fluid 25 in the containment chamber 22 is partially cooled by being partially surrounded by the cooling bath 28 which surrounds the upper portion of the containment chamber 22. The portion of the containment chamber 22 that is in contact with the wall 21 is not cooled. By convection, fluid 25 in the containment chamber 22 will move from relatively warmer areas to relatively cooler areas as illustrated by arrows 23. A liquid of significant water composition in a clean, smooth container, devoid of particulate that may cause crystallization, in combination with movement of the fluid caused by the aforementioned convection, will be cooled below the freezing point of the liquid while maintaining a liquid state.

Gaskets 24 reside between walls 21 so that the majority of the containment chamber 22 and the fluid 25 contained therein is insulated from ambient temperature. The containment chamber 22 is made of a rigid material that conducts cold from the cooling bath 28 to the interior of the containment chamber 22, which holds the contained fluid 25. The cooling chamber partially cooling the contained liquid 25 below its freezing temperature, in conjunction with the empty lower chamber 13 provide a cool liquid for a significant duration of time, a greater period of time than if the contained fluid were submersed entirely in a cooling substance.

FIG. 2 shows a portable, contained-fluid-cooling apparatus 100 in its closed state with lid 112 on and handle 114 folded down. On at least one side of the outer chamber 111 at least one opening 118 joins with an integrated containment chamber 120. The integrated containment chamber 120 is shaped to hold contained fluids, for example canned or bottled beverages 122. A vent 116 provides a means of relieving pressure between the interior of the apparatus and the ambient pressure so as to allow for easy lid-opening, as a cooling process on the interior of the apparatus tends to create a pressure differential.

FIG. 3 shows the portable, contained-fluid-cooling apparatus 100 with its lid 112 removed. The upper portions of the integrated containment chamber 120 meet the upper chamber 126. An opening 118 in the outer chamber 111 receives a contained fluid 122 such as a canned or bottled beverage.

FIG. 4 is a partial cutaway view of the apparatus 100 showing contained fluids 122 placed as intended in the integrated containment chamber 120 so that the contained fluids 122 are cooled by contact with a cooling bath 128 which surrounds a portion of the integrated containment chambers 120 in the upper chamber 126. Thus only the upper portion of the contained fluid 122 is cooled.

Gaskets 124 integrated with the integrated containment chambers 120 create a seal between the interior of the containment chambers and the exterior of the contained fluids so as to keep the contained fluids 122 insulated from the ambient temperature. The integrated containment chambers 120 are made of a rigid material that conducts cold from the cooling bath 128 to the interior of the integrated containment chambers 120. where the contained fluids 122 are stored. On at least one side of the outer chamber 111 at least one opening 118 joins with an integrated containment chamber 120. The integrated containment chamber 120 is shaped to hold contained fluids 122, for example canned or bottled beverages. A gasket 124 makes a seal between the integrated containment chamber 120 and contained fluid 122. The integrated containment chambers 120 extend from an opening 118 in the outer chamber 111 into the inside of the upper chamber 126 and the lower chamber 113.

FIG. 5 is a cross-section of the present embodiment 100. An apparatus and method for cooling a portion of a beverage container is described. The fluid-cooling apparatus 100 comprises an enclosure 111. The enclosure 111 further comprises an upper chamber 126 and a lower chamber 113. A containment chamber 122 is partially surrounded by walls of the upper chamber 120 and is further surrounded by walls 121 of the lower chamber 113. A cooling substance creates a bath 128 that is capable of producing temperatures below the freezing point of the fluid to be cooled, and is contained within the upper chamber 126 while the lower chamber 113 remains empty and uncooled. A beverage container 122 in the containment chamber 118 is partially cooled by being surrounded by the cooling bath 128 which surrounds the upper portion of the containment chamber 122. The portion of the containment chamber 122 that is in contact with the wall 121 is not cooled.
